SPECIFICATION forming part of Letters Patent No. 288,105, dated November 6, 1883.

Application filed August- 21, 1883.

exact description.

The invention consists in a draw-head provided with two link-apertures, one above the other, and with a U-shaped coupling-pin having two downwardly-projecting pins for cupling a link in the upper or lower link aperture.

The bottom shank of the U-shaped couplingpin passes through a curved slot or recess in the upper edge of a transversely sliding bar, by means of which bar the pin can be raised. Alinkraising frame is held to slide vertically in the draw-head, as willbe fully set forth here inafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

extended up ward, and has a slot at its upper end, through which slot a handle-lever, D,

passes, which rests in a transverse groove in the top of the drawhead and projects from one side of the draw-head, the said lever being pivoted to the draw-head at the opposite side. By lifting the lever D the frame 0 will be raised, as will also the link resting on the top or bottom cross-piece of the frame. The coupling-pin F is made U-shaped, and has a pin, F, projecting downward vertically from the end of each shank. The pin F is held on a vertical longitudinal slot in the draw-head. A bar, G, placed edgewise, is held to slide trans (No model.)

versely in the rear part of the draw-head, and is provided at one end with a check-lug, G, and at the opposite end it is pivoted to a connecting bar or rod, H, having a handle at its outer end and passing through avertical guideslot in'a downwardly-projecting arm, J, of the car. The bar H is provided in its bottom edge with notches a for locking the bar in the desired position on the arm J. If desired, the lower end of a lever, K, pivoted to the end of the car, is pivoted to the bar H to permit manipulating the bar H fromthe side of the car or from the platform. The sliding plate G is provided in its upper edge with a curved slot or recess, L, shaped as shown in Fig. 3, and forming aprong, L. The same result may be attained by locating the slot in the end of the plate, in

which case it will describe the arc of a large circle, its inner end curving downward. The bottom shank of the U-shaped part of the coupling-pin F passes through the curvedslot L, and if the plate G is drawn in the direction of the arrow c the bottom shank of the coup ling-pin will slide up the bottom curved edge of theslot, and thereby the pin will be raised and the link released, whether the same is in the top or bottom opening of the draw-head. If the plate G is moved in the inverse direc' tion of the arrow (1, it permits the pin to drop; or, if the spring L, which may bedispensed with, is provided, the pin will be drawn downward.

Having thus described-my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a draw-head having two link-openings, one above the other, of a U shaped coupling-pin, having a downwardly-proj ecting pin at the end of each shank, substantially as herein shown and described.

2. The combination, with a draw'head hav ing two 1lIlk-O1)BIllllgS, one above the other, of a U shaped coupling-pin, having a downwardly-projeoting pin at the end of each shank, and
